Air at 10°C and 80 kPa enters the diffuser of a jet engine with a velocity of 200 m/s. The inlet area of the diffuser is 0.4 m2. The air leaves the diffuser with a velocity that is very small compared with the inlet velocity. Determine the mass flow rate of the air in kg/s. Determine the enthalpy of the air leaving the diffuser in kJ/kg assuming variable specific heats. Show all work in your written submission. Input here the enthalpy.
